Bug Description

Tesseract fails with:

Error opening data file /usr/local/share/tessdata/eng.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
Failed loading language 'eng'
Tesseract couldn't load any languages!
Could not initialize tesseract.

when no eng.traineddata is present in "tessdata", even if a different language file has been specified. As far as I can tell, this was introduced in r760 (http://code.google.com/p/tesseract-ocr/source/detail?r=760&path=/trunk/api/tesseractmain.cpp) by the addition of api.Init call with NULL language (which defaults to 'eng'), and fixed in r811 (http://code.google.com/p/tesseract-ocr/source/detail?r=811&path=/trunk/api/tesseractmain.cpp).

Fixed in two ways. First, tesseract-ocr depends on tesseract-ocr-eng. Second, I just shipped new code with 3.04.00.
